** Description changed: After configuring screen energy saving in KDE, I noticed that after DPMS standby, my screen brightness is set to maximum. This is confirmed by `cat /sys/class/backlight/intel_backlight/brightness`. The problem can be easily reproduce by switching to standby manually using `xset dpms force standby`. Steps to reproduce: 1) echo "300" | sudo tee /sys/class/backlight/intel_backlight/brightness 2) cat /sys/class/backlight/intel_backlight/brightness This will report: 300 3) xset dpms force standby 4) Move mouse/press key 5) cat /sys/class/backlight/intel_backlight/brightness This will report 937 ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 4.1.0-3.3-generic 4.1.3 Uname: Linux 4.1.0-3-generic x86_64 ApportVersion: 2.18-0ubuntu7 Architecture: amd64 CurrentDesktop: KDE Date: Sat Aug 29 21:26:27 2015 InstallationDate: Installed on 2015-08-10 (20 days ago) InstallationMedia: Kubuntu 15.10 "Wily Werewolf" - Alpha amd64 (20150809) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) + --- + ApportVersion: 2.18.1-0ubuntu1 + Architecture: amd64 + BootLog: enabled, not active + CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' + CompositorRunning: None + CurrentDesktop: KDE + DistUpgraded: Fresh install + DistroCodename: wily + DistroRelease: Ubuntu 15.10 + DistroVariant: kubuntu + DkmsStatus: + virtualbox, 5.0.4, 4.2.0-10-generic, x86_64: installed + virtualbox, 5.0.4, 4.2.0-7-generic, x86_64: installed + ExtraDebuggingInterest: No + GraphicsCard: + Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a2e] (rev 09) (prog-if 00 [VGA controller]) + Subsystem: ASUSTeK Computer Inc.
